Why India’s Population Will Keep Growing Until the 2060s

The short answer

India holds about 1.47 billion people in 2026, more than any other country, and on the UN’s central projection it keeps growing for another 36 years. The peak lands around 2062, at roughly 1.70 billion. That is a further 231 million people added to a country that already has more than anyone. Taken on its own, that increase would slot in as the 7th largest country on Earth today, ahead of Brazil and everything below it.

The reason this surprises people is that India’s fertility rate is no longer high. It is 1.93 births per woman in 2026, below the replacement level of about 2.1 at which a population eventually holds steady. A country can be below replacement and still growing fast, and India is much the largest example of it in this dataset. The mechanism has a name: demographic momentum. The full trajectory sits on our India population page.

India crossed the fertility line years ago

On the UN’s estimates the average Indian woman had about 5.7 children in 1950. By 2000 that was down to roughly 3.3. The series first drops below 2.1 in 2020, and it has kept drifting down since. So by the time India reaches its peak in 2062, it will have spent roughly 42 consecutive years below replacement while never once ceasing to grow.

Four decades of too-few-births that still end with a bigger country sounds like a contradiction. It is not. Fertility describes how many children the average woman has. Population change depends on that number multiplied by how many women there are to have them, set against how many people die. In India both of those other terms still point firmly toward growth.

Why the momentum is so large

Look at the shape of the population rather than the rate. In 2024, about 42% of India was under 25. The single largest five-year band was the 20 to 24 year olds, roughly 130 million people, who are now moving through the years when most children are born. The youngest band, the under fives, numbered about 114 million, noticeably fewer.

That comparison is the whole story in one line. Births per woman are already falling, which is why the youngest group is smaller than the group ahead of it. But the number of women of childbearing age is near its all-time maximum, because they were born when fertility was still high. A smaller number of children each, multiplied by a much larger number of potential parents, still produces an enormous number of births. India records around 22,988,461 births in 2026, and is still projected to record about 18,961,897 a year in 2050.

The other half: hardly anyone is dying yet

Growth is births minus deaths, and India’s deaths are remarkably low for a country of its size. There are roughly 9,888,274 deaths in 2026 against those 22,988,461 births, a natural increase of about 13,100,187 people in a single year. Only around 7% of the population was 65 or older in 2024, so the age groups where most deaths occur are still thinly populated.

That changes, slowly and unavoidably. Life expectancy at birth is about 73 years now and is projected to reach roughly 80 by 2062, which holds the total up in the near term. But the very large cohorts alive today keep getting older, and annual deaths climb from 9,888,274 to about 17,363,384 by 2062, and overtake births entirely around 2063. Natural increase, that gap of 13,100,187 people a year today, has almost nothing left of it by then.

Where migration comes in

One common assumption is worth clearing away: India is not growing because people are moving in. It is a net sender of people in every year from now to the end of the projection, losing roughly 440,456 more residents to emigration than it gains in 2026, and about 14.1 million in total between now and the peak. India is projected to add 231 million people while continuously losing migrants, so the growth is entirely home-grown.

Emigration does get the last word on timing, though. In 2062 itself, births still exceed deaths, but only by about 222,433, while net migration subtracts roughly 388,026. The steady outflow that mattered so little during the growth decades is enough, once natural increase has worn down to nearly nothing, to tip the total over a year or so before births and deaths actually cross.

What the peak actually looks like

Nothing dramatic happens in 2062. India’s growth rate is about 0.86% a year in 2026, around 0.23% in 2050 and roughly 0.03% by 2060. The curve flattens out over decades rather than turning a corner, and the top is broad enough that the exact peak year matters less than the shape around it. By 2100 the annual change is about -0.51%, a slow decline rather than a collapse. We describe the same flattening at world scale in Is world population decreasing?

The contrast with China is instructive. China peaked back in 2021 and its fertility rate is about 1.03 in 2026, far lower than India’s. It holds roughly 1.41 billion people today and is projected to hold about 639 million by 2100, less than half. India passed China in 2023 and the gap widens from there. Our China page traces the other side of that divergence.

After the peak

India does not shrink dramatically once it turns. The projection has it at about 1.51 billion in 2100, still comfortably the largest country in the world and about 2.4 times the size of China, the second largest on our largest countries in 2100 ranking. India holds roughly 18% of humanity today and about 15% at the end of the century, so its share slips while its rank does not.

What changes far more than the headcount is the age structure. Median age is about 29 today, projected to be roughly 38 in 2050 and near 48 by 2100. The share of Indians aged 65 and over goes from about 7% in 2024 to roughly 30% in 2100. The country that is currently the world’s great reservoir of young workers spends the second half of this century becoming an old society, the same transition Japan and much of Europe went through earlier.

India is also not alone in its odd position. In this dataset 76 countries and territories are below replacement fertility today and still have their population peak ahead of them, the United States and Brazil among them. India is simply the largest, and it peaks 22 years before the world does, which we cover in When will world population peak?

How confident should you be in 2062?

The direction is safe; the date is not a promise. Fertility forty years out is the largest unknown, and the UN handles it with scenarios. On the low fertility variant India crests near 1.55 billion around 2046, more than a decade earlier and roughly 148 million smaller. On the high variant it is still climbing when the projection horizon runs out in 2100, at about 2.19 billion. Those bookends are a long way apart: the honest reading is that India crests somewhere between mid-century and the 2060s, at a total between roughly 1.55 billion and comfortably above the medium path’s 1.70 billion.

One asymmetry is worth flagging. In recent revisions of these projections, observed fertility has repeatedly come in below the previous estimate, in India as elsewhere. If that pattern continues, the peak arrives earlier and lower rather than later and higher. What none of the variants show is India shrinking soon. The youngest large cohorts are already born, already counted, and will be having children for another two decades whatever happens to the fertility rate.
